Sinus rhythm refers to the normal heartbeat rhythm generated by the sinoatrial (SA) node, the heart's natural pacemaker. It is characterized by a regular rhythm with a heart rate typically ranging from 60 to 100 beats per minute, and each heartbeat is preceded by a P wave on an electrocardiogram (ECG). This rhythm indicates that the electrical impulses are originating from the SA node, ensuring efficient and coordinated contractions of the heart. Maintaining sinus rhythm is crucial for effective blood circulation and overall heart health.

What is a sinus rhythm?
When the heart is functioning properly the sinus node controls the firing of action potential that contract the heart. When the sinus node dominates the heart will contract in a synchronized and effective rhythm This is called sinus rhythm.
Can you have normal sinus rhythm and sinus tachycardia simultaneously?
no
A sinus rhythm originate in?
Sinus nodes (sa nodes)
A sinus rhythm originates in the?
Sinus nodes (sa nodes)
What is a sinus rhythm and what other heart rhythms are there?
Sinus rhythm refers to a heart rhythm that is controlled by the depolarisation of the sinoatrial node. You can also have focal ectopic rhythms where random areas of the heart depolarise first and you can have supraventricular rhythms.
Can sinus rhythm be pulseless?
Yes, sinus rhythm can be pulseless in certain conditions, such as in cases of severe hypotension or cardiac arrest. While sinus rhythm indicates that the heart's electrical system is functioning normally, it does not guarantee effective blood circulation. If the heart is not generating sufficient contraction strength or if there is severe obstruction in blood flow, a person may have a sinus rhythm without a detectable pulse. This condition requires immediate medical intervention.
What does EKG showed NSR mean?
normal sinus rhythm
What is the name of rate set by the heart's pacmaker?
Sinus rhythm
What does the medical abbreviation SA-ECG mean?
Sinus rhythm .
What converts cardiac arrhythmia into normal sinus rhythm?
defibrillators
What does Predominant rhythm is sinus mean?
the beat of your heart when the beats goes up and down in a rhythm scale
What are the key differences between atrial fibrillation (afib) and sinus rhythm?
Atrial fibrillation (afib) is an irregular heart rhythm where the upper chambers of the heart beat chaotically and out of sync with the lower chambers. Sinus rhythm is a normal heart rhythm where the heart beats in a regular, coordinated pattern. Key differences include the irregularity of afib versus the regularity of sinus rhythm, as well as the potential for symptoms and complications associated with afib.
